FOSTER MILLIKEN, OF NEIV YORK, N. Y.

M ETALLIC POST.

SPECIFICATION forming part of Letters Patent No. 438,082, dated October7, 1890. Application filed July 31, 1890. Serial No. 360,540. (Nomodel.)

To all whom it may concern.-

Be it known that I, FOSTER MILLIKEN, of New York city, in the county andState of New York, have invented a new and useful Improvement inMetallic Posts, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in metallic posts; and the objectof the invention is to provide a strong and durable post composed of butfew parts and capable of being conveniently climbed when occasion maydemand; and a further object of the invention is to provide a meanswhereby the interior of the post will be adequately ventilated and madecapable of inspection and painting when desired.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 in a side elevation of a tapering post, illustrating theopen-work thereof. Fig. 2 is an elevation of the closed side of thesame. Fig. 3 is a transverse section through the post shown in Fig. 1,the section being taken below one of the tie-plates. Fig. 4 is a similarsection illustrating a slight modification in the manner of attachingthe sections of the post to the tieplates; and Fig. 5 is a transversesection through another modified form of post, in which the plates aredispensed with.

The post A is constructed of two or more segments 10, preferably two,which segments are provided at each side with a longitudinal ilange 11,extending outwardly at a right angle to the body, as is best shown inthe sectional views.

IVhen a post is to be constructed as illus trated in Fig. 1 and in thesectional view, Fig. 3, the concaved surfaces of the segments are placedface to face, and at desired intervals in the length of the postinverted-U-shaped tie-plates 12 are introduced between the flan ges ofthe segments. The tie-plates, when made U-shaped in cross-section, asshown,

consist of a fiat table-section ot and longitudinal iianged sections a',which extend downward from the under face of the table, as shown in theend View of the plate in Fig. 1. When the post is to be tapering, thewidth of the plates is varied to assist in imparting such a contour; butwhen a post is to be straight throughout its length the tie-plates areof uniform Width.

Between the flanges of the tie-plates, near each end thereof, a tube 13is introduced, and through the flanges of the segments and the anges ofthe tie-plates bolts 15 are passed, provided at one end With a head andat the other end with a suitable nut, or the said bolts may be providedwith nuts at both ends.

Between the tie-plates, secured in position as above described, a seriesof tubes 16 isV placed between the flanges of the segments, and bolts orrivets 15 are passed through said flanges and the tubes, as illustratedin Fig. 1, from which it will be observed the completed structureaffords upon two sides a perfect ladder.

In order to strengthen the segments 10 when they are of great length, alongitudinal rib 17 is formed integral with the central outer convexedsection of the segments, as illustrated in Figs. 3, 4, and 5 and also inFig.1; but the said strengthening-rib may be omitted or it may beemployed when short posts are con structed.

In the form of post illustrated in section, Fig. 4, the boltsaresubstituted by rivets 18 where the tie-plates are secured to thesegments and the tubes 13 are omitted, each flange of the segments beingseparately fastened to the flanges of the trusses.

In the form of construction illustrated in` Fig. 5 tie-plates areomitted and tubes 2O are interposed between the flanges of the seg`ments and studs 21 are passed through the flanges and tubes. When thestuds are in position, their ends are headed in place, forming thereby ahead at each extremity of the stud.

Having thus described my invention, I claim as new and desire to secureby Letters Patent@ 1. As an improved article of manufacture, a postconsisting of longitudinal hanged seg- IOO segments, substantially asand for the pur-v pose specified.

3. In a metallic post, the combination, with opposed segments providedwith longitudinal side anges and longitudinal strengtheningribs, oftie-plates or trusses, essentially U- shaped in cross-section,separating and spacing the segments, and rivets, bolts, or studsconnecting the members of the tie-plates or trusses with the flanges ofthe segments, substantially as and for the purpose specified.
